Document Hooke's Law for discussion on elasticity #5

Open jimmymcnulty opened 10 years ago

Elastic behavior in material follows several basic rules:

  1. The same amount of stress always produces the same strain.
  2. Sustaining a given stress produces a constant strain
  3. Removing a stress results in total recovery of strain.

Text should read:

In his 1679 experiments, English physicist Robert Hooke found that strain is proportional to the stress applied, up to a point called the elastic limit of the material. Beyond this limit, deformation is no longer recoverable and the material becomes plastic. Plastic yielding in most rocks is very limited, and the rocks may fail under stress by fracturing just beyond the elastic limit. However, wet, unconsolidated material can behave as a plastic.

The relationship between stress and strain as expressed by Hooke's Law:

stress / strain = a constant

Can't really deal with this right now because I'm a PO-lice.
